ICARUS: Interactive platform for Corpus Analysis and Research tools, University of Stuttgart

ICARUS [1] is a search and visualization tool that primarily targets dependency trees. It enables the user to search dependency treebanks given a variety of constraints, including searching for particular subtrees. Emphasis has been placed on a functionality that makes it possible for the user to switch back and forth between a high-level, aggregated view of the search results and browsing of particular corpus instances.

Please send questions and bug reports to icarus@ims.uni-stuttgart.de .

java -Xms1g -Xmx4g -jar icarus.jar

adjust the heap space parameters (Xms , Xmx) to your needs

After starting ICARUS the perspective view shows up. ICARUS comes with five different perspectives:

• Treebank Manager

• Development Usefull if you are going to develop an extension.

• Matetools-Parser

• Search-Perspective

• Weblicht

ICARUS Main Menu

The main menu is found in every perspective and offer the same functionalities:

• File:

  • Exit = Close the ICARUS platform

• Window: ICARUS allows the user to handle multiple Windows within the same session (e.g. one Treebank Manager Window and two Search Perspective Windows)

  • Close Window = Close the current focused window, if only one window is active ICARUS is closed
  • New Window = Open a new window
  • Copy Window = Generate a new window of the currently selected one (e.g. if the search perspective is active "copy window" result in another search perspective window)

  • Open Perspective = To switch to another perspective or just press the to open the perspective choose dialog

  • Close Perspective = Close the current focused perspective. ICARUS will not exit. If only one perspective is active the select perspective windowwill pop up.
  • Close all perspectives = Close all perspectives and the select perspective window will pop up. ICARUS will not exit.
  • Reset perspective = reset perspective

  • Preferences : open the ICARUS preferences dialog. Note: Preferences can also be accessed using the button in the different perspectives.

• Help:

  • About = Show the About ICARUS dialog (ICARUS build version, authors, contact options, EULA,...)

Below each perspectiv is the status bar .

• = Active tasks are displayed (with their description and progress bar) to the left of the memory consumption bar. Click to cancel the current task.

• = Shows the current memory consumption of ICARUS. Coloring changes from green to red. The dashed border is the threshhold when ICRUS shows a warning that it may run out of memory. (The parameters -Xms1g (start JVM size, here 1 gigabyte) -Xmx4g (maximum JVM size, here 4 gigabyte) can be used when starting ICARUS to change the JVM memory allocation)

• = If there are any active tasks (e.g. search tasks) you can click to get a list of all active tasks and may cancel them.
